2. APPLIANCE DATA
The efficiency of this appliance has been measured as specified in BS 7977 - 1 and the
result is as below :
Model
Efficiency % (Gross)
742 51
742 when converted to LPG. 54
The gross calorific value of the fuel has been used for this efficiency calculation. The
test data from which it has been calculated has been certified by Advantica Certification
services (0087). The efficiency value may be used in the UK Government's Standard
Assessment Procedure (SAP) for energy rating of dwellings.
The convertion of net efficiency to gross was achieved by
multiplying the net efficiency
by the following conversion factor from Table E3 of SAP 2005, rounding down to the
nearest whole number.
This product uses fuel effect pieces and burner compartment walls containing
Refractory Ceramic Fibres (RCF), which are man-made vitreous silicate fibres.
Excessive exposure to these materials may cause irritation to eyes, skin and
respiratory tract. Consequently, it is important to take care when handling these
articles to ensure that the release of dust is kept to a minimum. To ensure that the
release of fibres from these RCF articles is kept to a minimum, during installation
and servicing we recommend that you use a HEPA filtered vacuum to remove any
dust and soot accumulated in and around the fire before and after working on the
fire. When replacing these articles we recommend that the replaced items are not
broken up, but are sealed within a heavy duty polythene bag, clearly labelled as
RCF waste. RCF waste is classed as a stable, non-reactive hazardous waste and
may be disposed at a landfill licensed to accept such waste. Protective clothing is
not required when handling these articles, but we recommend you follow the
normal hygiene rules of not smoking, eating or drinking in the work area and
always wash your hands before eating or drinking. This appliance does not contain
any component manufactured from asbestos or asbestos related products.

3.2 In the United Kingdom, as supplied, the appliance can be installed in the
following situations: -
3.2.1 To a fireplace
complete with surround
and hearth as shown in
figure 1 and complying
with BS1251 after
removal of the fireback
and sufficient material
behind the fireback for a
debris catchment space.

Figure 1. Hearth and fireplace opening dimensions

3.2.1.1 ‘Hole-in-the-wall’ Installations
! It is recommended that a
hearth should be installed as in
section 3.9 (See figure 1).
! If a hearth is not fitted or a
reduced depth hearth is fitted,
the fire must be installed so that
the distance from the base of
the fireplace opening in the wall
to the finished floor level is at
least 100mm. Where there is no
floor covering or carpet and the
floor is of a type that is likely to
be covered in such a way in the
future then the distance from
the base of the fireplace
opening in the wall to the floor
level should be increased to at
least 175mm.
! To protect from the risk of
burns and ignition of clothing a
tactile separator shall be used. The hearth detailed in section 3.9 meets the requirements
for a tactile separator. If this is not used then a 672mm long fender, kerb, horizontal bar,
or other barrier, being fixed not less than 50mm above floor level and positioned
300mm in front of the fixing plane of the fire will meet the requirement.
3.2.2
To a fireplace incorporating a metal flue box complying with the constructional
requirements of the current edition of BS715. The dimensions of the flue box must
conform to those shown in figure 2.
3.2.3
To a precast concrete or clay flue block system conforming to BS1289 or BS EN
1806 with dimensions as in figure 3. The current versions of BS1289 and BS EN 1806
recommend that there should be an air space or insulation between the flue blocks and
the plaster because heat transfer may cause cracking on directly plastered flues.
However, generally this appliance is suitable for installations under all circumstances
unless there is a history of cracking problems.
Remember that faults such as cracking may be caused by poorly built and restrictive
flues, e.g. mortar extrusions, too many bends, flue heights below three metres,
restrictive terminations etc.
3.2.4 If the fireplace opening is greater than the acceptable dimensions given in this
guide, do not use the back of a fire surround or marble to reduce the opening. This may
cause cracking of the surround back or marble.

Figure 2. Metal flue box dimensions

3.3 Suitable flues and minimum flue sizes are as follows: -
It should be noted that, as with
many appliances, sharp bends
or horizontal runs in metal
flues at the top of the system
can be a cause of problems in
these types of installation.
! 225mm x 225mm
conventional brick flue.
! 175mm diameter lined brick
or stone flue.
! 200mm diameter factory
made insulated flue
manufactured to BS4543.
! 175mm diameter flue pipe.
See BS6461 Part 1 for suitable
materials.
! Single wall, twin wall or
flexible flue liner with a
minimum diameter of 125mm.
The materials to be used are
stainless steel or aluminium as
specified in BS715. The liner
must be sealed to the
surrounding area above the
fireplace opening and to the top
of the chimney. An approved
terminal must be fitted.
! A properly constructed
precast concrete or clay flue
system conforming to BS1289
or BS EN 1806. This system is
only suitable if the conditions
stated in section 3.2.3 are met.
3.4 The flue must conform to BS 5440: Part 1 in design and installation.
The flue, measured from the bottom of the fireplace opening to the bottom of the
terminal, shall be not less than 3m in actual vertical height. When calculated in
accordance with BS 5440: Part 1 Annex A, the minimum equivalent
height of the flue
shall be 2.0m of 125mm dia. flue pipe.

Figure 3. Precast or clay flue block system

3.5 The flue must not be used for any other appliance or application.
3.6
Any chimney damper or restrictor should be removed. If removal is not possible,
they must be secured in the open position.
3.7 If the appliance is intended to be installed to a chimney that was previously used
for solid fuel, the flue must be swept clean prior to installation. All flues should be
inspected for soundness and freedom from blockages.
3.8
If the fireplace opening is an underfloor draught type, it must be sealed to stop any
draughts.
3.9 The appliance must be mounted behind a non-combustible hearth (N.B.
conglomerate marble hearths are considered as non-combustible). The appliance can be
fitted to a purpose made proprietary class “O”-150°C surround. The hearth material
must be at least 12mm thick. The periphery of the hearth (or fender) should be at least
50mm above floor level to discourage the placing of carpets or rugs over it.
The surface of the hearth must be sufficiently flat to enable the bottom of the front
surround and the bottom front cover to be aligned horizontally. Any excessive
unevenness (uneven tiles, Cotswold stone, etc.) should be rectified.
The appliance must not stand on combustible materials or carpets.
3.10
The front face of the fireplace should be reasonably flat over the area covered by
the hotbox top and side flange seals to ensure good sealing. These faces should be made
good if necessary. The fireplace floor should be reasonably flat to ensure that a good
seal with the hotbox can be made.
Page 11
INSTALLER GUIDE
© Baxi Heating U.K. Limited 2006.

3.11
The minimum height from the base of the fireplace opening to the underside of any
shelf made from wood or other combustible materials is detailed below.
• For a shelf up to 150mm deep: Minimum height = 760mm.
• For a shelf deeper than 150mm: 760mm + 12.5mm for every 25mm depth over
150mm (See Graph 1).
3.12 Note that soft wall coverings (e.g. embossed vinyl, etc.) are easily affected by
heat. They may scorch or become discoloured when close to a heating appliance. Please
bear this in mind when installing.
3.13
This appliance must not be installed in any room that contains a bath or shower or
where steam is regularly present.
3.14
An extractor fan may only be used in the same room as this appliance, or in any
area from which ventilation for the appliance is taken, if it does not affect the safe
performance of the appliance. Note the spillage test requirements detailed further on in
this manual. If the fan is likely to affect the appliance, the appliance must not be
installed unless the fan is permanently disconnected.
3.15 Normal adventitious ventilation is usually sufficient to satisfy the ventilation
requirements of this appliance. In GB reference should be made to BS 5871 Part 2 and
in IE reference should be made to the current edition of IS 813 “Domestic Gas
Installations” which makes clear the conditions that must be met to demonstrate that
sufficient ventilation is available.

Graph 1. Combustible shelf clearances.

3.16
Propane gas appliances must not be installed in a room that is built entirely below
ground level (See BS 5871 Part 2).
3.17 If the appliance is to be fitted against a
wall with combustible cladding, the cladding
must be removed from the area covered by the
fascia. The cladding must also not touch the
fascia (See figure 4). We suggest that the fascia
is used as a template to mark the area for
combustible cladding removal and that this area
is increased by at least 2mm all round.
3.18 Proprietary terminals must comply with
BS 715 or BS 1289. Any terminal or
termination must be positioned in accordance
with BS 5440 Part 1 to ensure that the products
of combustion can be safely dispersed into the
outside atmosphere. Where the appliance is
connected to an unlined brick chimney it is
generally unnecessary for the chimney pot to be replaced or for a terminal to be fitted
unless the flue has a diameter smaller than 170mm.
3.19 The appliance is fitted with an A.S.D (Atmosphere sensing device). If the
appliance closes down after a period of operation for no apparent reason, the consumer
should be informed to stop using the appliance until the installation and appliance have
been thoroughly checked. The A.S.D will shut the appliance down if an unacceptable
amount of harmful products of combustion accumulate. Under no circumstances should
the A.S.D be altered or bypassed in any way. Only a genuine manufacturers replacement
part should be fitted. The individual A.S.D components are not replaceable.
3.20
A fireguard complying with BS 8423 should be fitted for the protection of young
children, the elderly, the infirm and pet animals.

5. FIREPLACE CHECK
5.1 Fireplace check.
5.1.1 Fireplace size
The fireplace must comply with the requirements described in section 3.2. This will
probably entail removing the fireback and infill material behind the fireback. The debris
catchment area shown in figure 7 must be kept clear of obstructions.
5.1.2 Fireplace general condition
The fireplace floor should
be reasonably flat to ensure
that the hotbox can be
installed without it rocking
and so that a good seal can
be made at the bottom front
of the box. The front face of
the fireplace should be
reasonably flat over the area
covered by the hotbox top
and side flange seals to
ensure good sealing. These
faces should be made good
if necessary. If the appliance
is to be fitted against a wall
with combustible cladding,
the cladding must be removed from the area covered by the fascia. The cladding must
also not touch the fascia (See figure 4). We suggest that the fascia is used as a template
to mark the area for combustible cladding removal and that this area is increased by at
least 2mm all round.
5.1.3 Soundness for appliance attachment
Two primary methods of retaining the appliance are provided: -
1) By fixing to the fireplace front surround.
2)
Using concealed tension cables fixed to the rear of the fireplace opening together
with secondary fixing to the fireplace floor.
The methods are detailed in section 9 of this manual. Before selecting the retention
method, consult with the customer. Method 2 is provided for instances where drilling
holes in the front surface of the fireplace surround is unacceptable to the customer or
otherwise impractical. N.B. It is unwise to attempt to drill into marble without the
proper tools and equipment.
If method 1 is chosen, make sure that the front surround area is sound enough to take
the wall fixing plugs and wood screws. If necessary, make sound with a suitable cement.
If method 2 is chosen, make sure that the areas at the back and towards the centre of the
Page 17
INSTALLER GUIDE
© Baxi Heating U.K. Limited 2006.
Figure 7. Fireplace area.

fireplace floor are sound enough to take the eyebolts and screws. If these areas have
deteriorated due to prolonged use, they should be made sound with a suitable cement.
5.1.4 Installations using a metal flue box
The whole of the top surface of the metal flue box must be covered with a minimum
100mm layer of mineral wool or equivalent insulation (See figure 2).
5.2 Fireplace flue pull.
Close all doors and windows in the room in which the appliance is to be installed. After
confirming with a match that smoke is drawn into the flue, light a 13 gram smoke pellet
and check that there is a definite flow through the flue. Verify outside that the smoke
exits from one terminal only and that the termination is suitable. Observe, where
possible, upstairs rooms and loft spaces for signs of escaping smoke indicating a
defective flue. If there is not a definite flow warm the flue for a few minutes and repeat
the smoke pellet test. If there is still no definite flow the flue may need remedial work –
Do not fit the appliance until there is a definite flow through the flue.
6. IGNITION CHECK
Before attempting to install, it is worth checking that the ignition system performs
satisfactorily.
6.1 Check ignition spark.
The pilot burner and electrode unit is at the left front of
the burner.
!Push in the right hand control knob and turn
anticlockwise through the ignition position marked
and up to the pilot position marked .
A spark should flash across from the pilot electrode to
the pilot burner tip. If there is no spark check the
following: -
! Ensure that the electrode lead is connected to the
terminal at the base of the electrode.
! If the above is correct, check for damage to the
electrode lead.

Figure 8. Ignition check

7. GAS SUPPLY CONNECTION
A nut and olive are provided for an 8mm pipe inlet connection to the ‘T’ connector at
the bottom front of the appliance. The ‘T’ connector can be rotated to allow a
connection from any direction but we strongly recommend a rear supply connection
only, as left and right hand connections from the front of the fire will prevent/restrict
manual control operation and access to the remote control sensor for battery
replacement. The ‘T’ connector includes a valve for isolating the gas supply and a
pressure test point.
The supply pipe must be rigid material. Flexible pipe must not be used.
Concealed supply pipe connection
If a concealed connection from inside the fireplace is required then, before the
appliance is fitted into the fireplace
it will be necessary to extend the supply line so
that it will project through the hole in the back of the hotbox and run to the inlet ‘T’
connector at the front. The pipe run from the supply line up to the rear opening in the
hotbox must be kept away from the area which will be taken by the hotbox when it is
installed (See figure 7).
Note that the centre of the appliance inlet ‘T’ connector is 25mm above the fireplace
floor. The inlet ‘T’ connector should be fitted to the supply pipe at this stage.
8. PREPARING APPLIANCE FOR INSTALLATION
IMPORTANT
Before continuing with the installation of this gas fire the aeration setting on
the burner must be checked. The aeration is factory set, but will require
adjustment. For Natural gas models see section 17.1 (Servicing and parts
replacement). For LPG models see the conversion guide supplied with the
fire.
1. Detach the burner unit from the
hotbox by removing two screws (See
figure 9). Lift the burner unit clear.
2. Fit the two “U” section seals to the
bottom edges of the hotbox side
flanges (See figure 10).
3. It is important that the grommet
supplied in the loose parts pack is
fitted to the hole in the rear of the
hotbox.
Page 19
INSTALLER GUIDE
© Baxi Heating U.K. Limited 2006.
Figure 9. Burner attachment points

For concealed connection only:
4. Pierce the grommet to allow the pipe to pass through it.
The grommet should envelop the pipe. If the hole is larger
than the pipe, seal it with tape. Do not pierce the grommet
unless the supply pipe is to pass through it.
5. The appliance is supplied with two fireback spacers. Do
not fit the fireback spacers if the fire is to be installed into a
precast or clay flue block system as in section 3.2.3. These
should extend backwards to ensure sufficient clearance from
the back of the fireplace. Remove the label and retaining
screws from the rear sides of the hotbox. Position the
fireback spacer as shown in figure 11. Secure the fireback
spacers using the screws removed previously and the two
supplied with the fire.
6. This appliance is supplied with a flue restrictor for
use where the flue draught is excessive. The restrictor
must NOT be fitted where a precast flue or a flue liner
is used. For all other installations the restrictor should
be fitted. There may however, be certain exceptional
circumstances where fitting the restrictor causes the
fire to fail the spillage test. In such cases the restrictor
will have to be removed. After removal conduct the
spillage check again.
The restrictor is packed loose with the appliance and is
fixed with two screws (See figure 12).
